Definitions
- the present disclosure relates to a non-immunosuppressive cyclosporin which binds to cyclophilin, which are cyclophilin inhibitors, in particular to their pharmaceutical use of in the treatment of Hepatitis C virus infection.
- the cyclosporins comprise a class of structurally distinctive, cyclic, poly-N-methylated undecapeptides, commonly possessing pharmacological, in particular immunosuppressive, or anti-inflammatory activity.
- the first of the cyclosporins to be isolated was the naturally occurring fungal metabolite Ciclosporin or Cyclosporine, also known as cyclosporin A (CsA).
- Cyclosporins which bind strongly to cyclophilin but are not immunosuppressive have been identified.
- PCT/EP 2004/009804, WO 2005/021028, or WO 2006/071619 disclose non-immunosuppressive cyclosporins which bind to cyclophilin have also been found to have an inhibitory effect on Hepatitis C virus (HCV).
- HCV Hepatitis C virus
- WO 2006/038088 incorporated herein by reference in its entirety, describes methods and compositions for the use of alisporivir in the treatment of HCV.
- Alisporivir (Debio-025 or DEB025 or DEB) is a cyclophilin (Cyp) inhibitor and its mode of action as an anti-HCV agent is via inhibition of host proteins, in particular of cyclophilin A, that are directly involved in HCV replication.
- Cyp cyclophilin
- Hepatitis C virus is an enveloped single stranded (+) RNA virus that belongs to the separate genus Hepacivirus of the family Flaviviridae .
- HCV causes acute and chronic liver disease, including chronic hepatitis, cirrhosis, and hepatocellular carcinoma.
- the current standard of care in HCV patients consists of a combination of interferon and ribavirin. Treatment duration and ribavirin dose depend on the genotype treated.
- Sustained viral response (SVR) in patients with genotypes 2 and 3 after standard of care treatment reaches 80-90%, but only 40-50% in patients with genotype 1.
- a slower response has been indicated as an important parameter to determine relapsers.
- side effects are significant and include myalgia, arthralgia, headache, fever, severe depression, leucopenia and haemolytic anaemia.
- myalgia, arthralgia headache, fever, severe depression, leucopenia and haemolytic anaemia.
- HCV Persistent infection by HCV, which has been identified as the major causative agent of non-A, non-B hepatitis has been considered closely related to liver diseases such as chronic hepatitis, liver cirrhosis or hepatocellular carcinoma. The development of these liver diseases is a major public health problem.
- cyclophilin inhibitors in particular alisporivir
- HCV Hepatitis C virus
- genotype 1, 2, 3 or 4 infection can be obtained when using alisporivir twice per day.
- the distinctive feature of alisporivir to interact with host rather than viral targets provides at least two advantages of clinical significance, like for example a high barrier for emergence of specific drug resistance mutations and efficacy in all HCV genotypes.

- a pharmaceutical combination comprising a first pharmaceutically acceptable formulation comprising alisporivir, a second pharmaceutically acceptable formulation comprising a direct acting antiviral agent, wherein the first and second formulations are packaged in a kit for the treatment of chronic hepatitis C infection.
- the standard of care treatment is a treatment that is used to treat Hepatitis C infections.
- the currently used standard of care treatment involves administration of interferon, in particular pegylated interferon in combination with ribavirin.
- non-responder is intended to mean a patient or subject who is a non-responder to standard of care treatment for HCV. More specifically, a non-responder to standard of care patient is a patient who has not responded to treatment with standard of care given over a 12 week treatment period.

- ⁇ RVR4LOD level of detection
- the IVRS/IWRS interactive voice response system / Interactive Web Response System
- the randomization scheme for patients will be reviewed and approved by a member of the Biostatistics Quality Assurance Group.
- Peg- IFNa2a and RBV treatment should not be interrupted because hyperbilirubinemia is not expected to be causally related to Peg-IFNa2a or RBV treatment.
- the next blood test is performed. If this test shows that total bilirubin is ⁇ 5 ⁇ ULN, the investigator instruct the patient to re-start alisporivir treatment (again, only if ALT is stable or improving).
- the maximum duration without alisporivir treatment is 2 weeks, either as continuous interruption or 2 separate weeks.
